Application filed October 24, 1904. Serial No. 229,784.

To all whom it may concern:

Be'it known that I, J OHN K. RIsnEL, a citizen of the United States, residing at VVil-v liamsport, in the county of Lycoming and State of Pennsylvania, have invented a new and useful Extension-Table, of which the following is a specification.

This invention relates to extension-tables, and has for its principal object to provide a novel form of table in which one or more auxiliary leaves are pivotally supported adjacent to the central portion of the table and in position to be adjusted to the plane of the top of the table when required.

A still further object of the invention is to provide an extension-table in which the auxiliary leaves are provided with independent supporting-braces so arranged as to form suppleme'ntalsupports for the main leaves or top of the table; and a still further object of the invention is to provide a table of the extension type wherein the auxiliary leaves may be readily moved to or from position from either side of the table and adjusted with ease and rapidity.

With these and other objects in view, as will more fully hereinafter appear, the inven tion consists in certain novel features of construction and arran ement of parts hereinafter fully describe illustrated in the accompanying drawin s, and particularly pointed out in the appen ed claims.

Inthe accompanyin drawings, Figure 1 is a pers ective view 100 ring from the bottom of a ta le constructed in accordance with the invention, portions being broken away in order to more clearly illustrate the construction. Fig. 2 is a longitudinal sectional elevation of the table with the auxiliary leaves folded away beneath the same. Fig. 3 is a similar view of the auxiliary leaves adjusted toform a portion of the top of the table. Fig. 4 is a transverse sectional elevation of the table on the line 4 4 of Fig. 3. Fig. 5 is a view similar to Fig. 3, illustrating a table provided with a number of auxiliary leaves.

Similar numerals of reference are employed to indicate corresponding parts throughout the several figures of the drawm s.

The main frame of the table comprises slidable rails of the interfitting rib-and-groove type commonly used in structures of this kind and s0 arranged as to slide on each other to permit extension of the table. To the end rails of the series are secured the per manent table-leaves 11 and the rail or apron 12, the structure being further braced and supported by transverse bars 13, to which the legs may be attached. The innermost bars 10 are connected at their opposite ends by transversely-disposed bracing-bars 14 and at the center by a bar 15, that extends up to a position immediately under the top of the table and affords a support for the adjacent edges of the permanent leaves 11 or the auxiliary leaves, as the case may be. To the in ner faces of the inner rails 10 are secured metallic pivot-plates 16, to Which are pivoted the opposite ends of cross-bars, two of such crossbars17 and 18 being employed for the support of each auxiliaryleaf 19. The cross-bars are connected to the auxiliaryleaves by hinges 20, and when adjusted to operative position said cross-bars are disposed at angles oblique to the vertical, inclining toward the center of the table and tending to maintain the auxiliary leaves in the positions to which they have been adjusted, while the upper edges of the cross-bars are beveled off, so that they may lie flat against the leaves when adjusted to the position shown in Fig. 3.

When in the inoperative position and folded beneath the tabletop, the auxiliary leaves are housed in the manner shown in Fig. 2. When it is desired to extend the table, the opposite ends are pulled outward, and one or both of the auxiliary leaves moved to the position shown in Fig. 3, the auxiliary leaves resting on the upper edge of the cross-bar 15, and the pivoted cross-bar 18 of each leaf affording a support for the adjacent edge of an additional leaf 19, as illustrated in Fig. 5, there being as many leaves as desired.

One of the principal advantages of the structure lies in the fact that the leaves can be adjusted to operative or inoperative position from one side of the table, owing to the practically continuous hinge formed by the bars 17 and 18. If a separate hinge member were placed at each side of the table, it would be practically impossible to adjust the section from one side of the table alone; but by the employment of the practically continuous hinges the leaf is at all times maintained in a horizontal plane.

Having thus described the invention, what is claimed is- 1. The combination in an extension-table,

of a frame including a transversely-disposed bar arranged below and serving to support the adjacent edges of the permanent tabletop, an auxiliary leaf, and pivotal supports for said leaf, the leaf being adjustable to bring one of its edges above the supportingbar, and one of the pivotal supports at the opposite edge of said leaf serving to support the adjacent edge of the permanent top.

2. The combination in an extension-table, of a frame including a centrally-disposed cross-bar arranged below and serving to sup port the adjacent edges of the permanent top, auxiliary leaves, and pivotally mounted cross-bars for the support of said leaves, the cross-bars being disposed on lines oblique to the top of the table when the leaves are adjusted to position for use.

3. The combination in an extension-table, of a frame including a transversely-disposed bar arranged below and serving to support the adjacent edges of the permanent tabletop, auxiliary leaves, and pivotal supports for said leaves, each of said leaves being adjustable to bring one of its edges above the supporting-bar, and one of the pivotal supports at the opposite edge of said leaf serving to support an additional leaf.

4. In an extension-table, the combination with a plurality of slidably-connected rails arranged in pairs, of a rigid cross-bar extending between the rails forming the inner pair,

and serving at all times as a support for two leaf-sections of the table-top, and an auxiliary leaf-section adjustable to the plane of the top of the table and arranged to rest on said cross-bar.

5. In an extensiontable, slidable extension side rails connected in pairs, a rigid cross-bar extending between the rails forming the inner pair, a plurality of cross-bars pivotally connected at their opposite ends to said inner rails and having their upper edges oblique with respect to their sides, and an auxiliary leaf pivotally connected to said pivoted cross-bars and resting on the rigid cross-bar when adjusted to a position in the plane of the top of the table, the oblique edge of one of the bars serving to support another portion of the table-top, and the pivoted cross-bars having their upper load-receiving edges in vertical planes to one side of the vertical planes of their pivots.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.

JOHN K. RISHEL.
